Parallel LCR Circuits
Procedure
Apparatus:
AC power source, Rheostat, Capacitor, Inductor, Reisistor, Voltmeter, Ammeter, connection wire etc.
Components:
- Resistor: A resistor is a two-terminal electronic component that produces a voltage across its terminals that is proportional to the electric current through it in accordance with Ohm's law.
- Lamp: A lamp is a replaceable component such as an incandescent light bulb, which is designed to produce light from electricity. These components usually have a base of ceramic, metal, glass, or plastic, which makes an electrical connection in the socket of a light fixture.
- Wire: A wire is a single, usually cylindrical, elongated string of metal. Wires are used to bear mechanical loads and to carry electricity and telecommunication signals. Wire is commonly formed by drawing the metal through a hole in a die or draw plate.
- Switch: In electronics, a switch is an electrical component that can break an electrical circuit, interrupt, or divert the current from one conductor to another.
- Battery: In electronics, a battery or voltaic cell is a combination of many electrochemical Galvanic cells of identical type that can store chemical energy and can deliver higher voltage or higher current compared to single cells.
- Voltmeter: A voltmeter is an instrument used for measuring the electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit; digital voltmeters give a numerical display of voltage by using an analog to digital converter.
- Ammeter: An ammeter is a measuring instrument used to measure the electric current in a circuit. Electric currents are measured in amperes (A), hence the name.
- Non-contact ammeter: A type of ammeter that need not be a part of the circuit.
Procedure:
- Select the components from the right side of the simulator.
- Connect them as in the figure: 1.
- Connection with wire is complete only when the black color appears at its ends.
- Change the frequency of the A.C. source and measure the current in the ammeter for each frequency.
- Plot a graph between frequency and current.
- Repeat the experiment for different values of R.
